SIDE BEARIN FOR RAIINV'AY-CARS.

Specification of Letters Patent.

Patented Sept. 14, 1915.

Application led March 17, 191.4. Serial No. 825,219.

To all whom t may concern:

Be it known that I, JOHNF. OCoNNoR,

` a citizen of the United States, residing at Chicago, in the county ofCook and State of Illinois, have invented a certain` new and usefulImprovement in Side Bearings for Railway-Cars, of which the following isa full, clear, concise, and exact description, reference being had tothe accompanying drawings, forming a part of this specification.

My invention relates to improvements in side bearings for railway cars.

The object ofmy invention is, to provide a side bearing of `durableconstruction" and efficient operation.

In the drawings forming a part of this specification, Figure lis an endview `of a body-*bolster and truck-bolster with the side bearingsembodyingfiny invention applied thereto. Fig. 2 is a plan view of one ofthe Vbearings partly broken away. Fig. 3 is a cross-section taken online A3 3 of F ig. 2.

Fig.` 4 is a longitudinal section takenon line 4 4 of Fig. 2. Fig. 5'isa Cross-section taken on line 5-5 of'Fig. 4.

Referring to the drawings, the numerals 6-6 indicate 'body-bolsters,joined bythe bearing bar 7. The .truck-bolster bearing bridge isindicated by the numeral 8. Upon one of the said bridges, preferably thebody side bearing bridge 7, is mounted a bearing plate 9. The sidebearing 10'comprises a base member 11, acradle 12, a roller 13, andV anaxle14. The base member 11 is preferably in general shape a hollowcylinder open above its longitudinal axis. At its base it is providedwith spaced-apart downwardly extended fl'anges 1'5-1-5 adapted to engagethe sides of the side bearing bridge Ato which it is attached; The meansof attachment'consisting preferably of rivets 16-16 which pass through'the bridge and through the lianges 15-15. Atv either end of the recess17 formed between the lianges 15,the base casting is preferably providedwith outwardly extended shoulders 18, each of the shoulders beingadapted'to Vrest upon the upper facey 19 of the side bearing bridge to whichthe bearing is applied. The cradle 12 is of a general rectangular shapein horizontal section, its lateral edges 20-20 being f shaped to conformto thecurvature of the -tened at its upper edge 25, the recess in whichit is received being substantially circular in cross-section in itslower portion, and havingan upwardly extending opening 26 ofsmallerdimension than the greatest diameter of the trunnion, to permitthe insertion of the trunnion in the recesses therefor when the cradleis sufliciently rotated. `within the base member, and to prevent theremoval ofthe cradle from the base member `when the parts are'in normal.assembled position on a car. Inorder to further secure the cradletrunnions in their bearings. and to prevent the accidental displacementthereof, the top of each recess 24 is preferably closed by a slug or bar27, the slug or bar 27 Vhaving angular ends 28-28 adapted to be receivedwithin the oppositely arranged slots 29 :.9 transversely extended in thewalls forming the upper portion 26 of the recess 24. On" mounting thecradle in the base member, the slug 27 which is preferably of metal. andsomewhat curved before its placing in positiom'is mounted in the recess26 and ydriven flat, so that the ends thereof ex- 'tendV into theappropriate slots just described. yThe upper face 30 of the slug is.when assembled in preferable arrangement. in the same plane as theadi-acont upper edges 31 of the base member. At either side. the cradleis provided-with perforations 33 within which the ends of theY axle 14are received. the axle'passing throughthe vperforation 34 provided inthe roller 13, and extending transversely of the side bearing bridge.

tion 33 may be upset and brought into engagement against the flat faces36 at the ends ofthe axle, to secure thev axle against rotation in theperforations 33--33 in the cradle, in order that the roller may revolveupon the axle, and a large bearing surface between the roll and axle beemployed. rI'he perforation 34 in the roll receives a bushing 38extended from end to end of the roll.l and which in preferableconstruction is made in-V tegral with the roller 13. f

The upper opening ofthe base member is 0f lesser Width than its sreateediameter between the oppositely curved walls, in order that the `cradlewhen mounted within the basememberucannot beaccidentally removed, itsremoval being edected through retatills' the Cradle veel ,elle end 0fthe Seme ie within the .i1-nner .Opening .of the base member, whereupon,and upon the removal ef the slugs 27, the Cradle may be Withdrawn The.depending flanges l5-115 0f the base member are v each provided ontheir inner faces with a yertical groove 4 0, which groove and the basemember when meente@ in position upon the side bearing bridge, form withthe adjacent 'faces et the bridge a vertical opening through which anyforeign material that may accidentally come Within the base member isdischarged.

In assembling the parts of the bearing, the roller. 13 is placed in theopening in the cradle`12, the axle 14 inserted through one of theperfo'rations 33 in the cradle, and through' the roller 13 until theaxle is brought to its proper position Within the roll, as illustratedin Eig. 3 of the drawingsfthereupon a punch or` other suitable tool maybe employed to upset the portions 37 37 of the cradle interveningbetween the perforation 33' and the adjacent perforations 35 at eitherend of the cradle, the upsetting tool being inserted in the perforations35 to secure) the engagement of adjacent portions of the 'cradle againstthe flattened faces near the ends of the axle 14; thereupon one'end ofthe cradle is inserted withinthe hollow in the base' member 11, androtated Y therein tol a'horizontal position. The slugs 27 when employedare then placed in posi-V tion, and thefbase 'casting mounted upon oneof the side bearing bridges. When mounted in its position upon theTcar,the roller 13 is adapted to be engaged by the opposed bearing-"plate '9.It will be apparent that the` ends of 'the axle 14.- are' thoroughlyinclosed When the parts are intlieir assembled relatin, and that thetrunni'ons 23 of the cradle are so inclosed'as to 'prevent'the 'lodgmento'f foreign material therein,Y and that by"'rea son of `the extension'of the' bushing' 38 throughout the roller, and the means employedtosecure the axle against rotation, that a large bearing surface Abetvveenthe axle and roller is-v secured, iifhich With the other featuresdescribed insures extremely slow Wear and a long life for the bearing.
